Study suggests cancer risk from depleted uranium研究表明，患癌症的風險，從貧化鈾
Depleted uranium, which is used in armour-piercing ammunition, causes widespread damage to DNA which could lead to lung cancer, according to a study of the metal’s effects on human lung cells.貧化鈾，它被用來在穿甲子彈，造成廣泛破壞的DNA ，可能會導致肺癌，根據一項研究金屬的影響，對人體肺細胞。 The study adds to growing evidence that DU causes health problems on battlefields long after hostilities have ceased.這項研究增加了越來越多的證據表明杜事業健康問題，在戰場上，只要在敵對行動結束後。
DU is a byproduct of uranium refinement for nuclear power.杜是一個副產品鈾細化為核電。 It is much less radioactive than other uranium isotopes, and its high density - twice that of lead - makes it useful for armour and armour piercing shells.這是少得多的放射性比其他鈾同位素，它的高密度-兩倍鉛-使為我所用裝甲部隊和穿甲砲彈。 It has been used in conflicts including Bosnia, Kosovo and Iraq and there have been increasing concerns about the health effects of DU dust left on the battlefield.它已經被用於在衝突中，包括波斯尼亞，科索沃和伊拉克，並已經有越來越多關注健康的影響，杜灰塵遺留在戰場。 In November, the Ministry of Defence was forced to counteract claims that apparent increases in cancers and birth defects among Iraqis in southern Iraq were due to DU in weapons.去年11月，英國國防部被迫反擊聲稱明顯增加，癌症和先天缺陷的伊拉克人之間在伊拉克南部因貧鈾武器。
Now researchers at the University of Southern Maine have shown that DU damages DNA in human lung cells.現在，研究人員在大學的南緬因顯示，杜損害DNA在人類肺癌細胞。 The team, led by John Pierce Wise, exposed cultures of the cells to uranium compounds at different concentrations.團隊，帶領由約翰皮爾斯明智的，暴露出文化的細胞，以鈾化合物，在不同的濃度。
The compounds caused breaks in the chromosomes within cells and stopped them from growing and dividing healthily.該化合物造成的休息，在染色體內的細胞，並停止他們的生長和分化健康的發展勢頭。 “These data suggest that exposure to particulate DU may pose a significant [DNA damage] risk and could possibly result in lung cancer,” the team wrote in the journal Chemical Research in Toxicology. "這些數據表明，暴露於微粒杜可造成重大[ DNA損傷]風險和可能導致肺癌， "團隊寫道，在Journal化學研究在毒理學。
Previous studies have shown that uranium miners are at higher risk of lung cancer, but this has often been put down to the fact that miners are also exposed to radon, another cancer-causing chemical.先前的研究表明鈾礦工人是在更高的患肺癌的危險性，但這種現象通常被放下來的事實，正在井下作業，也暴露於氡氣，又致癌的化學物質。
Prof Wise said it is too early to say whether DU causes lung cancer in people exposed on the battlefield because the disease takes several decades to develop.英明教授說，這是言之尚早，是否杜原因肺癌的人暴露於戰場，因為疾病需要幾十年的時間才能發展下去。
“Our data suggest that it should be monitored as the potential risk is there,” he said. "我們的數據表明，它應監測作為潛在的風險是存在， "他說。
Prof Wise and his team believe that microscopic particles of dust created during the explosion of a DU weapon stay on the battlefield and can be breathed in by soldiers and people returning after the conflict.英明教授和他的研究小組認為，微觀粒子的灰塵造成的，在爆炸案一名杜武器留在戰場上，可吸入由軍隊和人民回國後，這一衝突。
Once they are lodged in the lung even low levels of radioactivity would damage DNA in cells close by.一旦他們提出在肺，甚至低級別的放射性物質會破壞細胞中的DNA很近。 “The real question is whether the level of exposure is sufficient to cause health effects. "真正的問題是，是否暴露水平是足以造成健康影響。 The answer to that question is still unclear,” he said, adding that there has as yet been little research on the effects of DU on civilians in combat zones.這個問題的答案，目前還不清楚， "他補充說，有作為，但並沒有多大影響的研究杜平民在戰鬥區。 “Funding for DU studies is very sparse and so defining the disadvantages is hard,” he added. "經費，為杜研究是非常稀疏，所以界定缺點是很難， "他補充說。
